Arizona Election Highlights

Ducey is elected governor.

The Republican nominee, Doug Ducey, has won the governor’s race, filling the seat left by Gov. Jan Brewer, who is leaving office because of term limits. Mr. Ducey, the state treasurer, is a former executive for Cold Stone Creamery, the ice cream company. Despite his lack of experience in the public sector, Mr. Ducey characterized his position at the company as a valuable leadership role, and his campaign produced an advertisement that included testimonials from Cold Stone franchise holders. Mr. Ducey earned the support of high-profile Republicans, including Gov. Chris Christie of New Jersey, who campaigned for him in early October.

The Democrat, Fred DuVal, was an aide to President Bill Clinton and the chairman of the Arizona Board of Regents. He sought to cast himself as a palatable choice for Republicans in a state that often runs red, releasing a “G.O.P. for Fred” list that named nearly 200 Republicans supporting his candidacy. Mr. DuVal also tried to associate Mr. Ducey with the stances of those whom he called extreme conservatives, saying Mr. Ducey’s positions aligned him with the “Sarah Palin and Ted Cruz wing” of the party.

‘Right-to-try’ law is endorsed.

Arizonans voted to approve a proposition that would permit a manufacturer to make “a drug, biological product or device” available to a terminally ill patient if it has cleared the first phase of a clinical trial, meaning it would not need to be approved by the Food and Drug Administration. So-called right-to-try laws have been passed in other states, which could come into conflict with federal regulations. Ms. Brewer supported the measure.

Kirkpatrick wins House seat; Barber race still too close to call.

In one of the most competitive districts in the country, Representative Ann Kirkpatrick, the incumbent Democrat, clinched a narrow victory over Andy Tobin, the speaker of the Arizona House of Representatives, on Wednesday morning. Ms. Kirkpatrick won by just under 10,000 votes, more than twelve hours after the polls had closed. Over the course of the campaign, Mr. Tobin worked hard to tie Ms. Kirkpatrick to President Obama’s positions, particularly the Affordable Care Act, while Ms. Kirkpatrick criticized her opponent’s support for budget cuts in education and child welfare services, according to The Arizona Republic, which endorsed the Democrat.

In a rematch from 2012, Representative Ron Barber, a Democrat and former aide to Gabrielle Giffords, and Martha McSally, his Republican challenger, were locked in a dead heat on Wednesday, with Ms. McSally holding a narrow lead of just 36 votes. Both candidates have compelling biographies that helped make this repeat race a virtual toss-up throughout the campaign. Mr. Barber, who was by Ms. Giffords’s side when she was shot in 2011 and was himself seriously wounded, has carried the mantle of his former boss, campaigning to, among other things, curb gun violence. Ms. McSally is an Air Force veteran, and she was the first woman to fly a combat mission and command a fighter squadron.
